We divide 57721558 by 343
We want to figure out the number of times 57721558 can be divided by 343.

On to step 1:
If we divide 5 by 343, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 343

Going ahead to step 2:
If we divide 57 by 343, we get 0 and a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (7) of the dividend behind the 57 and repeat the process: 577 / 343

Moving on to step 3:
When dividing 577 by 343, we get 1 with a remainder of 234.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 234 after subtracting 343 from 577.
Bring next digit (2) of the dividend behind the 234 and repeat the process: 2342 / 343

Going ahead to step 4:
When dividing 2342 by 343, we get 6 with a remainder of 284.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 2058 from 2342 to get 284.
Bring next digit (1) of the dividend behind the 284 and repeat the process: 2841 / 343

Advancing to step 5:
2841 divided by 343 is 8 with a remainder of 97.
Put 8 as the next digit of the answer. 
Result so far: 168.0
The remainder is 97 after subtracting 2744 from 2841.
Grab the next digit (5) from the dividend, add it to 97, then carry on: 975 / 343

Step 6:
343 goes into 975 2 times with a remainder of 289.
Use 2 as the next digit of our solution. 
Result so far: 1682.0
Subtracting 686 from 975 leaves us with 289.
Bring next digit (5) of the dividend behind the 289 and repeat the process: 2895 / 343

On to step 7:
343 goes into 2895 8 times with a remainder of 151.
Record the quotient 8 as the next digit in the result. 
Result so far: 16828.0
Deduct 2744 from 2895 and we're left with 151.
Take the next digit (8) from the dividend and append it to 151, then repeat: 1518 / 343

On to step 8:
343 can be fit into 1518 4 times, resulting in a remainder of 146.
The number 4 becomes the next digit in our result. 
Result so far: 168284.0
Subtract 1372 from 1518 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

On to step 9:
1460 divided by 343 is 4 with a remainder of 88.
The number 4 becomes the next digit in our result. 
Result so far: 168284.4
The remainder is 88 after subtracting 1372 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
343 can be fit into 880 2 times, resulting in a remainder of 194.
The next digit of our result is 2. 
Result so far: 168284.42
If we take 686 away from 880, we end up with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Going ahead to step 11:
If we divide 1940 by 343, we get 5 and a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 168284.425
Subtracting 1715 from 1940 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 12:
343 can be fit into 2250 6 times, resulting in a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 168284.4256
If we take 2058 away from 2250, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 13:
1920 divided by 343 is 5 with a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 168284.42565
Subtract 1715 from 1920 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 14:
The number 343 fits into 2050 5 times, leaving a remainder of 335.
Write down 5 as next digit of the result. 
Result so far: 168284.425655
Subtracting 1715 from 2050 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

The quotient of the division is 168284.425655, and the remainder is 3.35e-05.
